A new eye test to reduce ghosting or double vision
Part of Brain & nervous system, Eyes & vision clinical trials.
This study tests a new way to reduce 'ghosting'—double or shadow images—that some people see, especially with astigmatism or at night. It involves using a special visual test to measure and possibly correct this effect.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your glasses or contact lens prescription must be between 0 and -5.00 (mild to moderate nearsightedness), including any astigmatism.
- You must have a small amount of astigmatism (less than -0.75 diopters).
- You need to have had an eye exam within the last 2 years.
- With your glasses or contacts, your vision must be at least 20/20 in both eyes.
- You cannot have lazy eye or any other eye disease.
- You cannot be taking any medications that could affect your eyes, or be in another eye research study.

This test checks if a new type of soft contact lens changes the thickness of a layer in your eye (called the choroid) after wearing it for just 1 hour. It may help understand how lenses could slow down nearsightedness.
This trial tests special contact lenses worn overnight to temporarily reshape the front of the eye, reducing nearsightedness during the day. It may help people who want an alternative to glasses or regular contact lenses.
This trial tests whether dual-focus soft contact lenses can slow down the worsening of nearsightedness (myopia) in young adults. If you're between 18 and 25 and your vision has been getting worse recently, this might help keep your prescription stable.
This trial tests special contact lenses that are designed to slow down the progression of nearsightedness (myopia) in adults. If you are 18-30, wear contacts, and your myopia has been worsening, this could be an option to help stabilize your vision.
This trial tests a new daily disposable silicone hydrogel contact lens for people with moderate nearsightedness. It will check if the lens is safe, comfortable, and gives good vision.
This trial tests a device that may help people who need reading glasses to see nearby objects more clearly without them. It could be an option if you have good distance vision but need help with close-up tasks like reading.
